v4l-utils side issues:

I'd have to apply my local bug fixes and submit the next version.

Kernel side issues:

There is a regression in the kernel related to FIMC-LITE
and FIMC-IS-ISP entities. Effectively currently it is only possible
to setup pipelines with S5C73M3 sensor to fimc.0.capture and
fimc.1.capture entities.

I would also have to rebase the patches for exynos4-is driver
for avoiding failure on open when the device being opened
has no connected sensor.
